It is a pure voltmeter with 7 measuring ranges: 1.5 \/ 3\/6\/15\/30\/60 \/ 150V AC. By adaptation resistances the value of the internal resistance could be changed.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eDue to the constant input resistance, the output power could be calculated: Output power (watts) = (output voltage * output voltage) \/ matching resistor\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe Multavi R was used to measure the output power of receivers and amplifiers, to adjust and measure the ripple voltages. \u003c\/p\u003e\u003cbr\u003e\u003cp\u003e \u003c\/p\u003e\u003cbr\u003e\u003cp\u003e \u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eWorking condition:\u003c\/strong\u003e Not tested\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMissing or damage:\u003c\/strong\u003e See description for details\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePictures: \u003c\/strong\u003eSee pictures for the cosmetic condition of this lot\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eBuying terms: \u003c\/strong\u003eSold as is!\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e \u003c\/p\u003e\u003cbr\u003e\u003cp\u003e \u003c\/p\u003e","brand":"Hartmann \u0026 Braun","offers":[{"title":"Default Title","offer_id":57350142525784,"sku":"KAY B-10-13570-bv-0","price":24.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/1987\/8232\/files\/hartmann-amp-braun-hartmann-braun-multavi-r-voltmeter-kay-b-10-13570-bv-5e667b04811d5.jpg?v=1779882433","url":"https:\/\/odnd.nl\/products\/hartmann-braun-multavi-r-voltmeter","provider":"ODND Vintage Audio Dreams","version":"1.0","type":"link"}
